As Allie sang her soothing tones to Ashlyn, the baby began to react in her sleep.

Now, music on its own is powerful, but music when channeled from sister to sister is probably even more impactful.

You see, in the video you’re about to watch, the girls’ mom didn’t just capture a moment, she also captured a memory, one that they can look back on and enjoy, but also one that could represent the moment their lifelong relationship as sisters truly began.

I’m sure one day they’ll be able to pinpoint this moment as the point in which their connection as siblings first started!

Ashlyn’s hands began to twitch; she raised a couple of fingers closer to Allie, almost as if trying to reach for the source of the singing. Then, her eyelids fluttered, and you can tell that even though the newborn was fast asleep, she could still hear her big sister’s voice.
